To all 'Ll/'700712, ift iii/Ly con/cern:

Be it known that I, HANS GoLDsoHMID'r, chemist, a subject of the King ofPrussia, German Emperor, and a resident of Essen-on-the- Ruhr, in theGerman Empire, have invented a new and useful Method of Dressing TinnedSheet-Iron Boxes, of which the following is an exact specification.

My invention relates to a method of and apparatus for dressing tinnedsheet-iron boxes by machines for the purpose of separating the surfacesof the boxes in equal manner on all sides. The following' conditionsmust, therefore, be fulfilled for practicing the matter: The boxes mustbe compressed, so as to occupy a small room only, and, furthermore, thedressing of the boxes must be so effected that the dissolving agent cancirculate at both sides of the plates from which the tin is to be takenoff. These conditions are fulfilled in my new method of dressing tinnedsheet-iron boxes, consisting therein that the boxes are pressed togetherbetween mechanically approaching and retiring surfaces and aresimultaneously or afterward perforated by suitable means.

ln order to make my invention more clear, reference is made to theaccompanying` drawings, in which Figure 1 shows a front View of aconvenient apparatus for practicing my method. Fig. 2 is a cross-sectionon line A B of Fig. l. Fig'. 3 shows another constructional form in sideview. Fig. 4 is a horizontal section of the apparatus according to Fig.3. Fig. 5 is a further constructional form in side view. Fig. 6 is acorresponding plan view.

ln the. drawings, c is the standard of the apparatus.

f f2 are tooth-wheels actuated by any con- Venient means driving' thepulley g, fastened to the axle of tooth-wheel f.

/t /t are two eccentrics fastened to the axle of wheelfz and moving' therods e' up and down. The rods e' are fastened at their lower ends to aplate 7e', guided in the frame by the guide-pieces Z Plate carries atits lower end a plate ato which points c c are detachably secured. is asecond plate strongly fixed on the standard e parallel to and oppositeplate a and being' provided with holes c/ c',into which the points c center in passing down. Z is a second plate between a, and 7), with holesin which the points c c may remain in their utmost position.

`a is a belt for feeding the box to be dressed, consisting' of singlestrips and arranged in corresponding' grooves of the rollers 'a a,mounted in frames n fr. The belt fa must be formed from single strips inorder to be not destroyed by the points c c.

The working of the apparatus is as follows: The boxes to be dressed arelaid down upon band n and by conveniently actuating' the rollers m arebrought upon plate N ow the plate a is nioved down, thereby compressingand perforating the boxes by means of the points c c. Now the plate orcarrier then vretires in moving upward, the plate Z frees the nowcompressed and perforated box from the upward moving point c, the bandfurther advances and carries the dressed box out of the apparatus, thebox being' now ready for taking off the tin and regaining the iron. Forsurely freeing the boxes from the upward moving points c the plate Z mayalso be moved down and approached to the plate L.

Fig. 3 shows an arrangement in which two rollers o 02 are provided withpoints upon their circumference andare arranged parallel to and neareach other, so that in turning' both rollers the points enter betweeneach other. y is a pulley actuated by any convenient means and drivingthe gears b2 7235", thereby rotating the rollers o 02. The boxes to bedressed are placed from above in the direction of the arrow, Fig. 3,between both rollers, are seized by the points and drawn in between bothrollers and leave the apparatus after being compressed and perforatedbeneath the rollers.

Figs. 5 and 6 indicate an apparatus consisting' of a plate r, a rollers, fitted out upon its circumference with points. The roller may berotated in any convenient manner, and in rotating' its points entercorresponding' holes in the plate fr. The boxes to be dressed are placedbetween r and roller s in the direction of the arrow, Fig. 5, are drawndown, and leave the apparatus after being' compressed and perforated.

The apparatus described only illustrates IIO some of the best devicesfor practicing my method and may be varied in different ways. Forinstance, instead of reciprocating the carrier It' by means ofeccentrics means may be devised which only raise the carrier 1, andthereby the plate e, and then release these latter, so that the carrier1, with its plate a, Jfalls down and acts in the manner of astamping-hammer. The free falling is, however, limited so that thesurfaces of the boxes do not touch each other, so as to allow tocirculate afterward the dissolving' agent on all sides of the plates.

I am aware that further changes in the form and proportion of parts anddetails of construction ot' the devices herein shown and described canbe made without departing from the spirt or sacrificing the advantagesthere- HANS GOLDSCHMXDT.
